Turboing my b16a, im confussed on what turbo would be best for my application, and what mean what.

i found 2 turbos both with a .48 a/r, ones is a 50 Trim, one is a 60 Trim. what is the difference.. im not sure what these numbers mean.

explains trim and a/r. also check the FAQs this is something that has been covered many times

basically the 60 trim is a "bigger" turbo and can make more power, all other things constant.

 

Read as much of the FAQ links as you can, or you shall be flamed a LOT in the future. Its an unwritten rule here that anyone who asks such a commonly-asked n00b question is free game.

Virtually every question has been asked here in the last 8 years, and is all in the search engine. Google "how to use a search engine" if you have issues.


For the question, the 50trim would get almost 400whp, which is almost the limit for pump gas, while the 60trim could make a little over 500whp with race gas. Using that .48ar turbine housing (hot side) will restrict you quite a bit, however, and you'd never get to those power levels.

If your goal is a stock motor/street car, get the 50trim. You'd get into the low 300's with moderate boost and decent tuning.

 

thank you for the explaination.. and thank god for google!

 

What are your goals with the car, REALISTIC goals and whats done to the engine or what are you doing. Generally in a honda vtec a .48a/r turbine runs out of breath higher in the revs so not a good choice. Generally a .63 a/r turine with a 57 trim e cover compressor is a pretty good all around performer on hondas. decent spool and nice power through the powerband but if you post up what your getting and what you wana do with the car it will help other reply properly.

 

well for now, without a built engine, im looking for around 250-275hp, im not sure how high you can go on stock internals.. maaybe the low 300's? on a good tune.

tho, i dont wanna push it to much, before i build the engine so prolly around 250hp.

Right now im just buying everything ill need to boost it a bit, but leaving plenty or room for more power/boost, so, no ebay manifolds or turbos. The engine is in an EF so theres a little bit of an issue with room, mainly the turbo manifold.. so ive opted for a spooling log mani, i know you cant make gobs of power with the log, but i think itll be good for what im aiming for.

 

With a good tune, quality setup and the right tuner, you can safely make 300whp on your stock B16. I would suggest a 57 trim; however, there are other turbos out there that would fit your needs better, but are a little higher on the price range. A GT3251E would be a great turbo for your setup and goals. It is very streetable and since it's still journal bearing, the price isn't bad. It should cost about $100 more than a standard Garrett 57 trim. If you want more info on it, PM TheShodan...he'll give you the rundown on it...

 

well here in canada, that $800 turbo, will cost me about $1000, unless the GT32 is worth $1000.
